OLD MONKS

Problem
There are monks in a monastry who don't speak(or communicate in any sense) with each other and have no have no mirrors or any reflective surface at their disposal. Evn the water they drink is from a "surahi" type pitcher(the opening is narrow and no reflection can be seen) and the floor is of extremely porous clay so that if u drop water to see reflection, the ground soaks it up so fast that it won't work.Now their leader is allowed to speak and he tells them that some monks have been infected with a disease that has marked their forehead and that they should leave of their own accord. But they are not told who is infected. If there are n monks how many days it takes for them to realise that they are infected and leave ?
